In this example, we will see how to refresh the application when the date is changed in angularJS.


  • First, we need to write the code for displaying the date picker in an HTML file.
  • We can achieve this by giving the input type as the date.
  • After completing the input type, we need to declare a function on the ‘onchange’ event so that whenever the date is changed or modified the application will be reloaded.
  • After declaring the function in the HTML file we need to write the function implementation in the ts file.
  • In the function implementation, we can use the window property of DOM, and we can call the reload function so that the application is reloaded.
  • After completing the above steps, serve or start the project.

Code Implementation:



import { Component } from '@angular/core';
    selector: 'my-app',
    templateUrl: './app.component.html',
    styleUrls: ['./app.component.css']
export class AppComponent {
    constructor() { }
    // Function to reload the application
    refreshPage() {



<h1>Hello User !</h1>
<p>Change the date to refresh the application.</p>
<input type="date" (change)="refreshPage()">



import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { FormsModule } from '@angular/forms';
import { AppComponent } from './app.component';
export class AppModule { }
